GermGuardian - AC4300WPT

I have a vertical germ guardian at the back of our LR4. I don't want it too close to the opening as it'll suck in too much dust and prematurely clog the filter. I wash the prefilter once a week..

I've got three Guardian HEPA towers. The oldest is seven years old now, and they still work great. I vacuum the charcoal filter once a week and change that and the HEPA filter about every six months.

Coway, GermGarurdian, and Blueair are all top rated. I personally have 2 blueair they work great I have 2 cats and my thanksgiving guests couldn’t smell them or their litterbox at all!

Germ guardian!! Have had one for about 10 years and the newest one about 7 years....they are work horses!

I bought a couple of Germ Guardian purifiers off of Amazon after Woolsey and they’ve performed well. 

I used a germ guardian but it was too loud so I diyed a few air filters for various types of fans and merv 8 filters. Not HEPA, but you can use higher merv ratings for cleaner air. Mine is not the same design as a Corsi-rosenthal box, but that was my original inspiration. DIY filters can filter a lot more CFM and are cheaper to maintain at the cost of elegance and aesthetic you get from commercial hepa filters. I can even turn it on and off remotely with a Kasa smart plug. You don’t have to use the 20x20 box fans that everyone uses, just need an adapter to connect the filter to the fan intake side (I made out of cardboard box)

I have a giant Shark he60601 and a smaller germ guardian. Shark is kinda for the whole space just for air quality/ dust. Germ guardian is for pets, it does seem to do everything it promises, less dust and dander.

I have the Germ Guardian one. Does a fine job.

I have that issue with a germ guardian right now. I tore it apart and the bearing is designed to be inaccessible. On its lowest setting I can't hear it anywhere in the house.

For a budget option I'm very satisfied with Germ Guardian. It's incredibly popular so there are a ton of knockoff filters available on Amazon and I've been able to thrift a stack of officially branded filters from Goodwill. Been running it for a few months. The first month the filter got nasty so I replaced it. Now the filter has been staying fairly clean for 3 months, there is no dust on my ceiling fans, and the vacuum is picking up a lot less. This is in a house with 2 cats.

There are lots of fraudulent bad air purifiers which are nothing but expensive fans out there. I have asthma, and have 3-4 purifiers of various different stripes throughout my home. Some are indeed better than others. Because i have asthma, I make sure that air purifiers do not have ionizers (which emit ozone and cause respiratory irritation). I use germ guardian, honeywell and shark. Depending on the size of the room, I try to get ones that fit the area in question. The current one I like is: # Honeywell AllergenPlus HEPA Air Purifier, Airborne Allergen Reducer for Large Rooms, Reduces Allergens, Smoke, Wildfire Smoke, Pollen, Pet Dander and More, Black, HPA200

Calgary, Alberta here. We are known for getting smoke from wildfires. The germ guardian purifiers have worked great for us to ease smoke that gets in. can be purchased at costco at least here in canada. no UV light but we didnt get it for that

GermGuardian is my favorite! Has a HEPA filter that is super easy to replace, UV-C, and odor control, and they also have some models with carbon filters, and is very quiet. I have one in my office and one at home and love them.

I have used ALEN and GermGuardian HEPA, I got the GG first and ALEN as a second one later. They definitely do something, I lived in city during first part of my pregnancy and the smells and air quality were stifling to me, so I bought one and it was a huge improvement as I could actually tolerate the air in my apartment without feeling sick. They filter noxious smells pretty well, I used to live with people who smoked 🍃and I was able to keep the smell out of my room with it, so it definitely did something. I always see Austin air and air doctor recommended, and some specifically for issues like mold. Idk if it’s hype, like someone said you could get a box fan and air filter and make your own. But, Air Doctor is doing a presale on their new model at half price so it’s around $400 instead of $800, but doesn’t come out until summer. I just bought it as i need one for other room and thought id see if it makes a significant difference compared to the ones i have.

Thirding the Coway rec. Replaced all my freestanding GermGuardian HEPAs a couple of years ago because the filters were too expensive and needed too frequent replacement. I do use Coway branded filters, which are pricier than third party knockoffs, but they cost less than the old GG ones and only need replacing once a year. I run mine at level 2 speed 24x7, no issues. Highly recommended.
